PHP Dev RFC Selecting Namespaces and Tag styles at include time.)


Forgive me - it's been a *long* time since I've used a listserv, and I'm
still getting the hang of getting the message tags exat. Reposting for those
who may have missed this because I got the exact format of the tags wrong
the first time around.
